Koller Products

Koller Products is a family-owned business specializing in the development and manufacture of pet products. Based in Fenton, Missouri, and having been in continuous operation since 1941, they are ranked as one of the top 100 injection molders in the USA, with manufacturing operations in Fenton, Missouri; Sullivan, Missouri; Gadsden, Alabama; Lenexa, Kansas; and Shawnee, Kansas. Koller is also credited with designing and producing the very first injection-molded desktop aquarium in 1985–a product now commonly found in millions of homes and office spaces around the world that continues to introduce both children and adults to the hobby. With leak-proof durability, the one-piece tank design did away with any worries about potential water damage caused by the leaking silicone seams on glass tanks. Koller combines intensive market research with world-class industrial design and engineering to create innovative products that address identified needs in the pet industry. Still considered one of the top aquarium manufacturers in the country, they remain focused on making it possible for every household to experience the enjoyment and relaxation of successful fish keeping.
